Anonymous is/was in a long distance relationship with her partner. 

She doesn’t have a huge appetite and eats small portions. While she was recently visiting her partner they got into an argument because of her eating patterns, with him saying that her breath smells bad as result of her not eating enough. 

He then said he can’t live with the odour of her breath, she left his place, tried reaching out later to speak to him about this but he doesn’t seem interested in discussing the matter further.
